Note:

* – Since input KS_2 (2nd knock sensor) is rarely used, by default it is connected to the ADD_I1 input, ie ADD_IO1 output can be used separately, and KS_2 can be used as remappable input ADD_I1. At this point ADD_IO1 can only work as an output. This configuration can be changed using jumpers on the PCB.

    В ответных разъемах MiniFit (что на провод) используются контакты N42W-T1.
    Пластиковая ответная часть разъема называется N42W-xx, где xx – число контактов разъема (например N42W-14 или N42W-06).
    N42W-T1
    N42W-12
